New features and changes introduced in this version are:
fmincon has a new algorithm called SQP for Sequential Quadratic Programming. The algorithm has the following features:
Honors bounds at all iterations
Attempts a different step if one leads to an objective or constraint function returning a NaN, Inf, or complex result
Fast internal linear algebra for solving quadratic programs
Choose the algorithm at the command line by setting the Algorithm option to 'sqp' with optimset. For more information about the algorithm, see fmincon SQP Algorithm in the Optimization Toolbox documentation.
The lsqnonneg solver no longer accepts a start point x0 as an optional input.
The Optimization Tool no longer has an input region for accepting a start point. If you import or run a problem that contains a start point x0, MATLAB issues a warning. Also, the Optimization Tool and lsqnonneg ignore x0, and instead use a start point of a vector of zeroes. If you export a problem structure from the Optimization Tool, there is no x0 field.
